Abstract: PROBLEM TO BE SOLVED: To satisfactorily control movement of a moving body, based on a pulse signal generated by a pulse generation mechanism with the rotation of a drive motor and detection outputs of position detection sensors for detecting that the moving body moves to a predetermined position. SOLUTION: An audio unit body 2 having a built-in speaker is vertically moved by the drive motor. The audio unit 2 becomes in an exposing state in which the display of a display unit body 3 is exposed, and in a screening state in which the display is covered and hidden. Based on a pulse signal generated by the pulse generation mechanism with the rotation of the motor and detection outputs of the position of the audio unit 2 by position detection sensors 29-32, a microcomputer controls the operation of the drive motor. The microcomputer detects a travel distance by counting the pulses of the pulse signal. Since the operation of the drive motor is controlled by using not only the detection outputs of the position detection sensors but the pulse signal from the pulse generation mechanism, movement of the audio unit 2 can be satisfactorily controlled, even when the position detection sensors become incapable of functioning, for example.

Abstract: PROBLEM TO BE SOLVED: To shorten a time required for discrimination by discriminating that a disk doesn't exist with a control part having a focusing error detection circuit and a tracking error detection circuit when a focusing error signal isn't obtained. SOLUTION: An optical disk presence discriminating device 3 makes the tracking error detection circuit 13 detect a tracking error signal from an optical pickup device 9 for tracking controlling the objective lens 9a of the device 9 for an optical disk 2. The device 3 judges whether or not the lens 9a is tracking-controlled for the disk 2 by a tracking control circuit 14 based on its error signal. The device 3 judges whether or not the lens 9a is controlled by a focusing control circuit 12 based on the focusing error signal. When the proper output of the focusing error signal isn't obtained, the device 3 processes as the disk 2 doesn't exist, and displays the effect on a display part 19 through a controller 17.
